Python script which will read a number from temp file, then append it to CSV file (I use this for my tradingbot to collect and store daily trading results)

read_from_txt-file_append_to_csv-file.py

# THIS PROGRAM WILL READ a NUMBER FROM TEMP FILE, THEN PLACE THAT NUMBER INTO A CSV (APPEND) FILE WITH DATE/TIME STAMP #
#
# NOTE: You may need to modify permissions/ownership of the folder where the files will be located
# To find out which user the python script is running as, comment out everything and just add these 2 lines:
# import getpass
# print(getpass.getuser())
#
# Modify folder ownership (if you are running the script on Ubuntu, most likely the username will be 'ubuntu'):
# chown -R ubuntu:ubuntu /path/to/folder/where/files/are
# Modify fodler permissions (read/write permissions to users/groups, read only to others)
# chmod 664 /path/to/folder/where/files/are
